Not true. The engines are mounted where they are, to prevent that.

Besides the high cost of DU ammo, there's an environmetal issue with
dust created by projectile impact. Scary stuff.


Which is why they now use tungsten projectiles.

I really don't understand the "environmental issue." Those rounds are
meant to melt through armor and shatter into pieces which bounce around
inside the tank and function as an anti-personnel weapon. That's fairly
high on the "toxicity" scale compared to DU which is approximately as
radioactive as common rock.
